How Dr. Heather Sandison Discovered LiveO2
A naturopathic doctor heard about it from two directions at once. Within weeks, she couldn’t ignore the results.
Dr. Sandison Tells Her Story
How one colleague and one patient changed her entire approach to oxygen.
Dr. Heather Sandison is a naturopathic doctor who specializes in brain health and cognitive decline. She didn’t find LiveO2 in a textbook. She found it because the results kept showing up in the people around her.
It Started with a Colleague
A fellow doctor bought a LiveO2 system for her clinic. She never brought it in. She kept it at home because her own athletic performance improved so much she didn’t want to give it up.
That got Dr. Sandison’s attention. Here was a physician — someone trained to be skeptical — who bought a device for her patients and then kept it for herself. Not because the data looked good on paper. Because she felt the difference every time she used it.
That’s the kind of signal doctors pay attention to. When another clinician can’t stop talking about their own results, something real is happening.
Then a Patient Showed Up with Results
Around the same time, one of Dr. Sandison’s own patients found LiveO2 on his own. Within about a month, he saw huge changes.
Cognitive function improved. Chronic fatigue lifted. Sleep got better — something they weren’t even trying to fix.
“When this started happening to a couple of people around me … I decided it would be negligent to not start incorporating LiveO2 into my own practice.”
— Dr. Heather Sandison, NDTwo people. Two completely different use cases. Both getting results that were hard to explain with anything else. That was enough.
From Curiosity to Clinic
By January 2018, Dr. Sandison had made up her mind. She reached out to Mark Squibb — the inventor of LiveO2 — to understand what was actually happening inside the body.
She put it simply: people were getting profoundly better using something she’d never heard about in medical school. That gap between what she was seeing and what she’d been taught demanded answers.
“Here was this device that was so profoundly helpful — how did I get more people on it?”
So she brought LiveO2 into North County Natural Medicine. Not as an experiment. As a core part of her treatment approach.
Why Doctors Pay Attention
Dr. Sandison didn’t adopt LiveO2 because of a sales pitch. She adopted it because the evidence walked through her door.
Cognitive function. Her patient’s thinking got sharper within weeks. That’s the kind of change that’s hard to get with supplements or medication alone. Read more about oxygen and cognitive performance.
Chronic fatigue. Energy came back. Not a caffeine spike — real, sustained energy from better oxygen delivery at the cellular level. How oxygen restores energy after chronic disease.
Sleep. This was the surprise. Nobody was targeting sleep. But when your body gets more oxygen, your nervous system calms down and sleep cycles regulate on their own.
Athletic performance. Her colleague’s results were so good she never even shared the device with patients. That’s not a placebo response — athletes know the difference between feeling good and actually performing better.
The Brain Connection
Dr. Sandison specializes in brain health and cognitive decline. So when she saw cognitive improvements happening this fast, it aligned with something she already knew: the brain depends on oxygen more than any other organ.
Your brain uses roughly 20% of your body’s oxygen supply. When circulation drops — from age, inflammation, or vascular damage — the brain is the first thing that suffers.
LiveO2’s Adaptive Contrast protocol pushes oxygen into areas where normal breathing can’t reach. That’s why the cognitive results Dr. Sandison saw were so fast. She wasn’t just giving her patient more oxygen. She was reopening the pathways that deliver it.
Common Questions
Dr. Sandison is a licensed naturopathic doctor who specializes in brain health, cognitive decline, and age-related neurological conditions. She founded North County Natural Medicine and is a recognized voice in integrative neurology.
Within about a month of using LiveO2, her patient experienced improved cognitive function, reduced chronic fatigue, and better sleep — results they weren’t even targeting when they started.
Most users report noticeable changes after their first session — clearer thinking, more energy, better mood. Deeper improvements like sleep and sustained energy typically build over the first few weeks of consistent use. Learn more about the timeline.
Yes. LiveO2’s BrainO2 protocol is designed specifically for brain oxygenation. It uses Adaptive Contrast to drive maximum blood flow to the brain, then floods it with high-concentration oxygen.
Dr. Sandison was drawn to LiveO2 because the results showed up in real patients without her involvement. She didn’t prescribe it — people found it on their own and got better. That kind of organic evidence is what clinicians trust most.
